Consistency and change in personality were analyzed by examining personality types across adulthood and old age using data from two nationally representative panel studies from Germany (N = 14,718; 16 – 82 years) and Australia (N = 8,315; 15 – 79 years). In both samples, the Big Five personality...

Individuals are expected to mature with increasing age, but it is not yet fully understood which factors contribute to this maturation process. Using data of a representative sample of Germans (N = 14,718) who gave information about their Big Five personality traits twice over a period of 4...

The death of a spouse is an extremely stressful life event that consequently causes a large drop in life satisfaction. Reactivity to the loss, however, varies markedly, a phenomenon that is currently not well understood. Because lack of controllability essentially contributes to the stressful...

Perceived control is an important variable for various demands involved in successful aging. However, perceived control is not set in stone, but rather changes throughout the life course. The aim of this study was to identify cross-sectional age differences and longitudinal mean-level changes as...

Does personality change across the entire life course, and are those changes due to intrinsic maturation or major life experiences? This longitudinal study investigated changes in the mean levels and rank order of the Big Five personality traits in a heterogeneous sample of 14,718 Germans across...

Social norms are central to theoretical accounts of longitudinal person-environment transactions. On the one hand, individuals are thought to select themselves into social roles that fit their personality. On the other hand, it is assumed that individuals' personality is transformed by the...

The Motivational Theory of Life-Span Development (MTD) identifies motivational and self-regulatory strategies that people use to meet the challenges they face throughout life. The theory distinguishes control strivings related to goal engagement from those related to goal disengagement and goal...

How socio-cultural contexts shape individual functioning is of prime interest for psychological inquiry. Secular increases favoring later-born cohorts in fluid intelligence measures are widely documented for young adults. In the current study, we quantify such trends in old age using data from...

Recent research has repeatedly demonstrated that well-being typically evinces precipitous deterioration close to the end of life. However, the determinants of individual differences in these terminal declines are not well understood. In this study, we examine the role of perceived personal...

Anticipating one's future self is a unique human capacity that contributes importantly to adaptation and health throughoutadulthood and old age. Using the adult lifespan sample of the national German Socio-Economic Panel (SOEP; N 10,000, age range 18-96 years), we investigated age-differential...
